The new Series 2 is not a re-design, it's an evolution.
The Series 2 range has been systematically engineered to deliver an unprecedented drinking experience. Still keeping your drinks cold for 24 hours or hot for 12 hours.
Just like the original Chilly's Bottles, the Series 2 bottles are 100% leak-proof - and they come with a new, improved design. The o-ring seal in the lid is built in, which means that your bottle is sealed even more securely.
